Download or read book Daylight Performance of Buildings written by Marc Fontoynont and published by Routledge. This book was released on 2014-05-01 with total page 311 pages. Available in PDF, EPUB and Kindle. Book excerpt: As part of Daylight Europe, the daylighting behaviour of 60 buildings was observed and measured during a three year period. Buildings of many different types, sizes and ages were included - from offices to museums, libraries, churches, houses, airports and factories; from Classical buildings to modern constructions, and from a small single room to an office of over 100,000 square meters. The results of the study of each building are presented, extensively illustrated in colour, with the unusual features and main lessons highlighted. The book also includes details of the monitoring procedures, the results of and comparisons with simulations, the outcome of post-occupancy evaluation, and a summary of the major findings. These show the extraordinary potential of daylighting techniques to improve amenity and energy performance for the benefit of the occupants and building managers. They also demonstrate how often opportunities are missed, and the frequency of problems of overheating or glare. Above all, they demonstrate the beauty, elegance and scope of daylight design.

This book was released on 2011 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Atria have proliferated in a range of contemporary buildings and daylighting is perhaps their most valuable aspect. This thesis is an exploration of the effects of atrium facades on the daylight performance of an atrium and its adjoining spaces. It examines the effects of atrium wall surface reflectance distribution patterns, different surface types, and the location, size and proportion of fenestration and opaque areas in an atrium's facade. The study seeks to provide knowledge that would be most useful at the early design stages of a project. The study uses Daylight Factor (DF) and Average Daylight Factor (ADF) to examine daylight levels in an atrium building. Chapters Two and Three develop an understanding of key daylighting concepts and consider specific daylight linked atrium parameters related to this study; atrium geometry and enclosing surfaces each of which is examined through an extensive literature review. Chapter Four demonstrates the effects of reflectance distributions and diffuse and specular surfaces on DFs across the atrium floor using physical scale models. Following this, in Chapter Five, the experiments are repeated using RADIANCE and results from the two methods are compared to establish their accuracies. ADF values, calculated using Littlefair's (2002) algorithm, are also compared with those obtained from physical scale model and RADIANCE. Chapter Six establishes the range of atrium well indices in which surface reflectance distributions affect DFs. This then informs the experiments of Chapter Seven which ascertain the influence of different facade compositions (with variable and even fenestration from the atrium roof to its floor) on daylight availability in atrium buildings. To contextualise work undertaken in this thesis, the research findings are compared with data from real buildings. Finally, specific conclusions with regards to the effects of atrium facades on daylighting in atrium buildings are drawn before more wide-reaching inferences are made.
Download or read book Annual Dynamics of Daylight Variability and Contrast written by Siobhan Rockcastle and published by Springer Science & Business Media. This book was released on 2013-06-25 with total page 89 pages. Available in PDF, EPUB and Kindle. Book excerpt: Daylight is a dynamic source of illumination in architectural space, creating diverse and ephemeral configurations of light and shadow within the built environment. Perceptual qualities of daylight, such as contrast and temporal variability, are essential to our understanding of both material and visual effects in architecture. Although spatial contrast and light variability are fundamental to the visual experience of architecture, architects still rely primarily on intuition to evaluate their designs because there are few metrics that address these factors. Through an analysis of contemporary architecture, this work develops a new typological language that categorizes architectural space in terms of contrast and temporal variation. This research proposes a new family of metrics that quantify the magnitude of contrast-based visual effects and time-based variation within daylit space through the use of time-segmented daylight renderings to provide a more holistic analysis of daylight performance.
Download or read book Quantification of Luminous Comfort with Dynamic Daylight Metrics for Energy efficient Residential Buildings written by Peng Xue and published by . This book was released on 2016 with total page 143 pages. Available in PDF, EPUB and Kindle. Book excerpt: The design for daylighting innovates continuously as there have been fruitful researches aiming to bring more light into the room and make it more comfortable. Therefore, it is necessary to predict the luminous comfort level with some metrics which can be easily obtained. Based on the questionnaire survey, the second part provides climate-based daylight modeling and simulation of 108 unit cases to quantify the luminous comfort. Considering the actual climate for the selected building site, dynamic daylighting performance metrics are also studied. The statistical analysis found these two metrics, uniformity and Ave. DA300 (Daylight Autonomy), could be complementary to each other and have significant correlations and indications for luminous comfort. The benchmarks of these two metrics were also studied which make it possible to predict residents' luminous comfort without the post-occupancy evaluation. Hong Kong is situated just south of the Tropic of Cancer and receives a lot of sunshine which could generate more lighting energy savings and bring solar heat gain at the same time. Many researchers focus on the total annual energy consumption with the balance of both lighting energy and cooling loads. The third part of this thesis appealed that the energy-efficient design should guarantee residents' luminous comfort level first. Based on the second part, two luminous comfort zones were proposed and the units with higher value of these two metrics, in comfort zone 2, have a great potential of energy saving by compromising daylighting performance. A new metric EDR (Energy Daylight Ratio) was also proposed to reflect the relations between daylighting performance and total energy performance. Case study was conducted to optimize the green features' design and validate the utilization of the metric. The result showed the luminous comfort metrics could guide and help optimize the facade and energy-efficient design at the early stage.

Download or read book A Study Of Daylight Modeling Approaches Applied In LEED written by Maryam Esmailian and published by . This book was released on 2021 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Across various versions of USGBC Leadership in Energy and Environmental Design (LEED), the intent of the Daylight Credit has always been to connect building occupants with the outdoors and reduce the use of electrical lighting by introducing adequate daylight into the space. However, the credit requirements and assessment methods have evolved over time. The most recent version of LEED (v4.1) provides three options for assessing the Daylight Credit. The first two options are based on computer simulation, whereas the third relies on physical measurement. Option 1 performs annual simulation of "Spatial Daylight Autonomy (sDA) and Annual Sunlight Exposure (ASE)." sDA indicates the sufficiency of daylight inside a room and ASE shows the potential risk of visual discomfort. Option 2 adopts a point-in-time approach, which demonstrates through computer modeling that a sufficient area of a space will have illuminance levels between 300 lux and 3,000 lux at both 9 a.m. and 3 p.m., on a clear-sky day at the equinoxes (15 days within September 21st and March 21st). Option 3 is based on measurement of the illuminance level in the physical space rather than computer simulations. Another major difference among the options is that Option 1 fully adopts the Climate-Based Daylight Modelling (CBDM) approach, predicting hourly daylight quantity on an annual basis, including the application of interior shades when direct sunlight enters the space, while Option 2 and Option 3 measure daylight performance on some days and hours, with no consideration of interior shading. In LEED v4.1 there are some changes in performance thresholds in comparison to LEED v4 such that all options can now provide 3 points maximum. According to USGBC (E-mail interview, 2020) Option 2 is used most often among certified projects. This research focuses on the first two options in order to assess whether their results are in line with each other, and to find out whether a space which contributes to points in one option would also contribute if the other option is applied, given that Option 1 and Option 2 adopt totally different approaches. To this end, an office space model, located on the ground floor of a building with dimensions of 30 feet x 30 feet x 10 feet and a WWR of 40%, was simulated under the conditions of Option 1 and Option 2. The simulations were run in 5 different cities, considering a variety of window orientations and two different interior shading devices as well as with and without an overhang. The findings of this study clearly show that significantly different results can happen between the two simulation approaches for quantifying the percentage of a space that is daylit for the purpose of evaluating LEED credits.

Book excerpt: To complement the critical and objective view gleaned from the study of some sixty buildings, this design manual has been developed to provide a more synthetic approach to the principles which lie behind successful daylight design. These principles are illustrated with examples drawn from the case study buildings. The emphasis throughout has been on practical methods to improve design, rather than techniques studied for any intrinsic interest. The book provides the necessary tools to assist the designer to provide well daylit interiors, and shows that good daylight design is not a restriction on architectural expression but, on the contrary, acts as an inspiration and foundation for good architecture.
